1、不定式分句作主语补语时通常带to,但在某些句型中也可省略to.例如：
All I did was empty the bottle.
All you do is talk about cars.
What I really wanted to do was drive all night.
The only thing I can do now is go on by myself.
上述诸例中的不定式分句之所以能省略to,有一个条件,即主语部分必须具有一个主动词do,这个do可以是限定动词形式,也可以是非限定动词形式,而且不论什么时体形式均可.
2、it has to do是省略了引导词that的定语从句.关系代词that代替先行词all,在从句中作do的宾语,所以可以省略.have to do是英语习语,意为“与XX有关”.
这里的stop我认为应该是all it has to do的一种用法
Now all it has to do惟一要做的
例句All it has to do is wiggle its tongue once, and people fall over in a faint.
首先你得弄清句子的成分：Now all it has to do 是主语，is是谓语，stop raining位于be动词is之后，因此是表语！而在主语Now all it has to do 中，it has to do 又作定语修饰不定代词all !所以整个句子的意思是现在他全部不得不做的就是停止训练！has to 是have to 的三人称单数形式，意为“不得不”...

收起
Stop 后加动名词(V+ ing)表示把一正进行中之事终止, 所以是用动名词.
如果要用不定式, 则代表停止手中正进行之事, 转去做另一件事 e.g. After his speech, he stopped to listen the comments from his professer.
